Description

[Detailed description of the invention] The present invention relates to a flooring material with a core material such as a honeycomb core, which is lightweight, has excellent heat insulation performance, and provides a flooring material in which the core material and the surface material are in strong adhesion. be.

Conventional flooring materials are manufactured by using plywood or particle board as a substrate, pasting a decorative material on the surface, and then performing actual processing on the edges of the substrate.

However, with such a configuration, it is not possible to obtain thermal insulation performance, and it is necessary to prepare a separate insulation material such as glass wool and install it in a separate process before installing the flooring material, which reduces costs and time. It was a huge disadvantage. In addition, plywood and particle board are heavy, so thick and strong materials must be used closely to support them.

The present invention solves the above-mentioned problems and attempts to obtain a lightweight flooring material with excellent heat insulation performance by using a substrate made of a core material such as a honeycomb core and a thin plate material. Moreover, the edge of the core material is pressed and bent in order to strengthen the adhesion between the core material and the plywood.

The present invention will be explained in detail below with reference to the drawings.

First, as shown in FIG. 1, a frame material 2 is placed around the four circumferences of a core material 1 that is partitioned into a large number of cells by partition walls partitioned in the thickness direction of a honeycomb core, roll core, etc.
Place.

As shown in FIG. 3, the edges of the front and back partition walls of the core material are pressed and bent to increase the bonding area with the surface material.

The frame material has the same thickness as the core material whose front and back edges are pressed and bent, and the lateral sides thereof are actually processed as shown in FIG. This actual processing is usually performed after the floor material is formed, but it may be performed on the frame material if necessary.

Next, as shown in FIG. 4, thin board materials 3 are bonded together via an adhesive 4 so as to cover both the core material and the frame material to form a composite floor material 5.

The adhesive is applied to the core material and frame material side, but not to the board material side, so as shown in Figure 4, there is a part of the board surface that does not come into contact with the core material where no adhesive is present. arise. Therefore, the amount of adhesive used is gradually reduced compared to conventional products, and it is also possible to prevent adverse effects on the flooring material due to changes in the adhesive over time.

The material of the core material 1 can be paper, resin-impregnated paper, synthetic resin film, metal sheet, or any other arbitrary material, and the front and back edges of the core material are pressed and bent to make the front and back surfaces of the core material smooth and bonded to the thin plate material. make it good.

The frame material 2 is usually made of wood, but is not limited thereto.

As the thin board material 3, plywood, particle board, synthetic resin board, etc. with a thickness of about 2 to 5 mm are used.

Note that any surface decorative material 5 such as veneer or decorative sheet may be attached to the surface of the thin plate material.

The adhesive is appropriately selected depending on the materials of the core material, frame material, and thin plate material.

The thickness of the core material is preferably 7 to 15 mm, and 7 mm
If it is less than 15 mm, sufficient heat insulation performance will not be obtained, and if it is more than 15 mm, compressive strength and impact resistance will be insufficient. By filling the voids in the core material with a fibrous material such as Dallas wool or a foam such as polyurethane foam, complete heat insulation and sound insulation performance can be obtained. However, if the thickness of the core material is 7 mm or less, sufficient insulation performance can be obtained by filling it with Dallas wool, etc., but the strength required for flooring materials such as impact resistance cannot be obtained. Undesirable.

The composite flooring material of the present invention having the above structure has the following effects.

Since air is trapped within the independent cells of the core material, insulation performance is achieved, making it possible to perform insulation without using a separate insulation material.

The weight of the flooring material is 1/2 to 1/3 that of conventional products, making installation work easier.

By pressing and bending the edge of the partition wall of the core material, the bonding area becomes larger and the adhesion between the core material and the plate material becomes stronger. At the same time, the amount of adhesive used is reduced, reducing costs and pressing time. This makes it possible to shorten the length and prevent deformation of the flooring material over time.
